Reviewer's Responses to Questions

Comments to the Author

1. Does this manuscript meet PLOS Digital Health’s publication criteria? Is the manuscript technically sound, and do the data support the conclusions? The manuscript must describe methodologically and ethically rigorous research with conclusions that are appropriately drawn based on the data presented.

Reviewer #1: Yes

Reviewer #2: Partly

Reviewer #3: Yes

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception. The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

Reviewer #2: Yes

Reviewer #3: Yes

Reviewer #1: A topic and clinically relevant article concerning a cluster randomized trial assessing the effect of a digital health algorithm on quality of care in Tanzania (DYNAMIC study) indicating the potential value of such technologies.

Reviewer #2: 1.The study has certain significance and application value for the health management of a certain population with this digital CDSA .

2.Please indicate the detailed source of the statistical software, as well as the scope of application and reference standards of the statistical methods used in this study.

3. Some language writing (spelling and grammatical) needs to be corrected in the manuscript. Some sentences are too long and difficult to understand.

Reviewer #3: A cluster randomized trial assessing the effect of a digital health algorithm on quality of care in Tanzania (DYNAMIC study)," several areas need attention.

First, the introduction should clearly articulate the specific research gap this study addresses and succinctly state the primary objectives and research questions. This will help readers understand the importance and relevance of the study within the broader field of digital health interventions. Additionally, more comprehensive details should be provided on the ePOCT+ digital clinical decision support algorithm (CDSA), including its functionalities and how it was integrated into routine care. This should also cover the training and mentorship components of the intervention, which are critical to understanding the intervention's implementation and effectiveness.

The statistical methods section would benefit from a more detailed explanation, including how missing data were handled and the rationale for using specific statistical models and covariates. This will enhance the robustness of the methodology and make it easier for readers to assess the validity of the findings. Furthermore, the presentation of results could be improved by using more visual aids, such as tables and figures, to summarize key outcomes and differences between the intervention and control groups. This approach would make the results more accessible and engaging.

In the discussion section, a deeper exploration of the study's findings and comparisons with similar studies would be valuable. The authors should provide potential explanations for the observed outcomes and discuss the implications for future digital health implementations. Moreover, a thorough discussion of the study's limitations, including potential biases and their impact on the findings, is necessary for transparency and to guide future research. Consistency in terminology and formatting throughout the manuscript will also enhance clarity and readability. Finally, a detailed data availability statement should be included to specify where and how the study data can be accessed, promoting transparency and reproducibility. Addressing these areas will significantly strengthen the manuscript, making it a more compelling and impactful contribution to the field of digital health.
